"We were hopeful with the time missed with a virus, things would settle down in his knee," GM Paul Holmgren said.

But that didn't happen.

Holmgren said Pronger would have some "loose bodies" cleaned out; he called the surgery a "maintenance" procedure and said the knee was otherwise sound.

Holmgren also announced that Brayden Schenn would be recalled from the Phantoms, and that Andreas Nodl was placed on waivers.

Pronger and Andreas Lilja will go on the long-term injured list.

Jaromir Jagr, rehabbing after a groin injury, sklated Monday and there is a chance he will play Friday in Anaheim. James van Riemsdyk, another injured winger, is a longshot to play this weekend, Holmgren said.
